Virgil's engineering logbook from the trenches.
Three compiler gaps close in a single day. Supervised receive timeouts land on a feature branch. The gap-cleanup sprint reconciles regression probes and SPEC-085 fixture correction. Graf object.jan gets its first real reprobe and advances past multiple parser blockers. The compiler is eating its own tail.
Actors v2 Stage 1 lands on unstable. Payload-bearing message variants compile end-to-end. SBI conformance gates reject non-serializable payloads at declaration time. Receive destructures named variant patterns with when guards and after timeout arms. SPEC-029 send safety integrates with ActorRef sends. Plus the WASI/browser carrier merge and a zb throttle fix.
The :cluster actor production sprint closes. SPEC-021 §4.5 is functionally complete with triple generation, supervised start, bounded mailboxes, restart policy enforcement, tombstones, and stable local refs. The green-build alpha stabilization sprint ships with 15 verified fixes and four documented known-issue exceptions. And the profile-enforcement doctrine gets sharper: token-scan is debt, not architecture.
